A Time of Delivery Contract (TOD) is a form of a power purchase agreement. Energy may be sold at a specified, contracted price. Some contracts may have an obligation to serve electricity on a daily or annual basis.
The Energy Price Schedule determines when the energy can be sold for a specified rate. Select Define a 12x24 energy price or import an annual price profile. Annual price profiles can be imported using one of several Import formats that HOMER Front recognizes.
If you would like to consider changes in price over your project lifetime, select the Price Escalator (%/yr) option and specify %/yr or select the Escalation by year to enter %/yr.
You can apply a daily or annual contractual obligation to meet your export obligations.
Select the Define daily obligation requirements to enter a daily schedule. You can customize your daily export requirements by weekday or weekends and assign a start and end date. Choose the start and end hour and specified energy export obligation (MWh/window).
You may also import an annual delivery profile using one of several Import formats that HOMER Front recognizes.
The contracted capacity is the percentage of the exported energy that is allocated to the contract after Capacity Market obligations are met. Any remaining exported energy is allocated to the energy markets. If your contract does not include an annual daily obligation, select select Percent contracted capacity and define a percentage of the contracted solar, storage, and wind capacity in %.
